Answer:
This indicates that the chances of the mean life span today is greater than 70 years is 0.5871
Step-by-step explanation:
The past year showed an average life span of 71.8 years.
Population standard deviation = 8.9 years
We are supposed to find the mean life span today is greater than 70 years
i.e. P(X>70)
Formula :
Z=−0.202
P(X<70)=0.4129
P(X>70)=1-P(X<70)=1-0.4129=0.5871
Hence This indicates that the chances of the mean life span today is greater than 70 years is 0.5871
Answer:
O A.
Step-by-step explanation:
To find the equation of the line, we need to know the slope and the y-intercept.
so, let's start by the slope. We need two points given in the graph.
(4, 5) and (-2, -3)
Then use the Slope-Formula to identify the Slope of the line.
m = slope
m = Slope Formula
m = subtract the second y from the first y / second x from first x
m = Turn the fraction to positive because two negatives = positi-
m = Simplify
m = Final Answer
The slope of the line is now what about the y-intercept?
The y-intercept is located at the y axis.
It determines how many units the graph goes up or down depending...
Well in this case, the y-intercept is negative because it is below on the yaxis
Then we must determine the y-intercept.
so we know is negative but it isn't exactly on a point so it is formed as a fra-
then we can determine it by seeing when it hits another unit (hard explainin)
y-intercept = -1/3
Final Answer: y =
